QUESTION: Dear Trey,
I've heard several times over the past year or so, that there’s almost no vitamins or any other nutrition left in say, the spinach salad I just ate earlier today? Is this true? ...and if so, why and how is it any different from the spinach salads I've been eating for the past 40 plus years. —Irien F, Rhode Island.
ANSWER: "Due to soil depletion, the practice of GMO use, plate ETA etc; crops grown decades ago were much richer in vitamins and minerals than what most of us consume today"
Would it be an over statement to say; "that morning grapefruit, afternoon apple or evening kale-spinach-brocklie salad you had today contained very few nutrients"? ...not to mention some of the other less healthy foods I'm sure you likely eat. Well non the less, it is indeed TRUE, that fruits and vegetables grown decades ago were much richer in vitamins and minerals than the varieties most of us consume today. The main culprit in this disturbing nutritional trend is soil depletion: Modern intensive agricultural methods have stripped increasing amounts of nutrients from the soil in which the food we eat grows. Sadly, each successive generation of fast-growing, pest-resistant carrot is truly less good for you than the one before.
1992 Earth Summit statistics indicate that the mineral content of the world's farm and range soil has decreased dramatically.
In June of 1992, an Earth Summit Report was issued in RIO that documented the decline in numbers of various rare and endangered species, enlarging holes in the ozone layer, disappearance of tropical rain forests and indigenouss peoples - yet the most important and immediate crisis factor the human race was glossed over and relagated to the rear pages of the voluminous report - the dcline of nutritional mineralsin farm and range soils by continent over the last hundred years. The results of the Earth Summit report on the decline of mineral values in our farm and range soils show tht North America (United States, Canada and Mexico) is far more affected than all other continents.
Percentage of Mineral Depletion From Soil During The Past 100 Years, by Continent:
North America - 85%
South America - 76%
Asia - 76%
Africa - 74%
Europe - 72%
Australia - 55%
